I am on a business connection with Spectrum, I have 5 static IPs assigned but they only seem to work when I plug in their own very low end router. The problem is, their router is too low end to handle our traffic level and overheats/crashes constantly, we have tried multiple different replacements (of the same model) and they all did the same. We have a high end Cisco router we would like to use instead, but of course, when we plug it into the modem, we are not assigned our Static IPs.
Is there any way we can recieve them without using their assigned router?
